No, you have to remove it from gstconfig.h. It's a bug in the
gstconfig.h shipped with ossbuild. The QtGStreamer build system was
based on the assumption that it is built on top of GStreamer >=
0.10.31 which  has an updated gstconfig.h that doesn't require libxml.

Fyi, CMAKE_INCLUDE_PATH is not added to the compiler command line. It
is used as a hint for find_file() cmake calls. If you really really
want to fix this in QtGStreamer instead of just updating your
gstconfig.h, you need to add a FindLibXml2.cmake file, use
find_package(LibXml2) in the top level CMakeLists.txt and add the
found include path in the compiler include path with the
include_directories() call.
